<div><p>The Flight Recorder plugin enables you to view JFR recording files.</p>
<p>The JFR runtime engine dumps recorded data to files with the jfr extension. These JFR recordings are binary files for viewing in the JDK Mission Control (JMC) client.</p>
<div class="infoboxnote" id="GUID-40FF6634-CBCF-4879-A494-52FF7CEFD759__GUID-3E49C8FE-5301-4B09-9F3E-B893E48E5D16"><p class="notep1">Note:</p>Java SE Development Kit (JDK) 7 update 4 or later version is required to view JFR recordings.</div>
<p>The recording file is automatically opened in the JMC client when a timed recording finishes or when a dump of a running recording is created. You can also open any recording file by double-clicking it or by opening the <span class="bold">File</span> menu, selecting <span class="bold">Open File</span> and locating the necessary recording file in the file system explorer.</p>
<p>This topic describes general procedures for viewing the recordings in the JMC client. For information about how the data in various tabs is organized, see Flight Recorder Tab Reference.</p>
